Getting “Cannot verify client. (3000)” when trying to upload archive from Xcode to itunesConnect

Question

Just updated to Xcode 7.1 and getting this error. Was able to upload fine using 7.0.1

Answer 1

Same problem here. Grabbing a cup of ☕️ worked for me.

Answer 2

I first tried to upload and got the "cannot verify client"-error. Then i did a validate, which was successfull and then again a upload which also was successfull. No restart etc. needed.

Answer 3

1. I remade the app with "App Store" provisioning profile. Earlier it was "Ad-hoc" provisioning profile.
2. I submitted the app from "Application Loader" instead of traditional "Organizer".

Above two steps enabled me to submit the app to iTunes Connect for beta testing also. There is always an element for surprise whenever apple releases an updated XCode.

Answer 4

For what it's worth: I got this error when my startdisk was almost full (less than a few hundred MB left).

Cleaning up some space and re-submitting resolved this issue.

Answer 5

From the rest of the answers it seems that a lot of different things "resolve" this issue. Here are the particulars of what solved it for me:

1. The iPad had to be plugged in.

2. The iPad had to be signed in (i.e. not locked).

After I satisfied those two conditions, it validates and uploads reliably. If either one isn't done, I am not able to validate or upload to iTunesConnect and I get the Cannot verify client (3000) error.

Answer 6

When it fails two times in a row, choosing "Validate" and after that "Upload to App Store" does the trick for me.
